Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Recruitment will be accomplished using a 2-phased process. Phase I. An invitation letter explaining the study purpose and its relevance to oral health in a correctional setting will be mailed to the inmate population at two Federal Bureau of Prisons' institutions who entered the prison system during the first half of 2009. Dublin, a female FCI located in Northern California and Butner, a male FCC located in North Carolina were the selected facilities due to the high incidence of drug abusers among their inmates. The letter, which will invite all inmates to participate in the study, will inform the inmate should they consent to participate in the study that they will have their existing dental record confirmed, Central File reviewed for DSM-IV diagnosis pertinent to the study, and that they will be given a study questionnaire. Positive responses to the invitation letters will be returned to Dr. Johnson at head quarters in Washington DC. The psychology division will code the volunteer inmates into the three study groups.
Phase II. The first 30 chronologically documented volunteers in each study group category will be scheduled an appointment. A consent form will be read and explained to each inmate, in either English or Spanish as appropriate and his/her signature obtained as his/her informed consent.
Each question on the study questionnaire will be read to the inmate volunteer and the Research Associate will record the answer. A retrospective comparative study will then be employed utilizing the inmate's initial dental intake exam (routinely administered by the Federal Bureau of Prisons' dental department). The dental chart will be abstracted for dental caries. The pattern of surface-specific dental caries (DFS index) will be described and analyzed. The focus will be on the levels of untreated and treated disease diagnosed in a 4-zone partition of the oral dentition, representing a modification of the zones identified in the Grainger's caries severity index scoring system as this partition allows focus on decay patterns of anterior tooth surfaces. The multivariate summary of disease levels within each zone will be derived and statistically compared across the three study groups using Hotelling's t2-test (the multivariate extension of the Student-t test). The results of the study will be used to do a preliminary assessment between methamphetamine drug abuse and oral health and determine whether a prospective clinical study is warranted.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Age between 18 and 65.
* At least 16 existing natural teeth, root tips included. The reason for choosing this relatively high number is in order to have sufficient data for an analysis of patterns of decay.
Exclusion Criteria
* History of Sjogren's syndrome or similar exocrine disorders, as documented by health history
* Currently in active orthodontic treatment
